Abstract: |
The survey was undertaken using four Bartington Grad601 sensors mounted at 1m intervals (1m traverse interval) onto a rigid frame. The system was programmed to take readings at a frequency of 10Hz (allowing for a 10-15cm sample interval) on roaming traverses (swaths) 4m apart (Illus 6). These readings were stored on an external weatherproof laptop and later downloaded for processing and interpretation. The system was linked to a Trimble R12 Real Time Kinetic (RTK) differential Global Positioning System (dGPS) outputting in NMEA mode to ensure a high positional accuracy for each data point. MLGrad601 and MultiGrad601 (Geomar Software Inc.) software was used to collect and export the data. Terrasurveyor V3.0.37.0 (DWConsulting) software was used to process and present the data Headland Archaeology (UK) Ltd was commissioned by Neo Environmental Ltd (the Client), to undertake a geophysical (magnetometer) survey of a site covering approximately 111 hectares, west of Beccles, Suffolk where a solar farm is being proposed. This geophysical survey report will be submitted as part of a planning application for the proposed Beccles Solar Photovoltaic (PV) array and associated infrastructure development. The results will also inform future archaeological strategy, if required. The survey has identified a range of anomalies consistent with modern activity and agricultural usage of the proposed development area (PDA) but also of uncertain and of possible archaeological origin against a largely homogenous magnetic background. Five small clusters of magnetically enhanced ditch and pit-like anomalies, possibly indicative of enclosures, are identified on the lower ground at the eastern peripheries of the two separate land parcels that comprise the PDA. Two of these clusters lie adjacent to a ditch and former trackway (Gull Lane) and a further two groupings lie close to areas of medieval common land. Very high magnitude anomalies indicative of localised burning, anomalies of uncertain origin and a possible area of localised extraction are also recorded. A group of linear trend anomalies and two areas of magnetic enhancement of uncertain origin identified at the northernmost part of the PDA may locate a former area of extraction. The survey has also recorded the location of several former boundaries and regular patterns of field drains. The sites of the demolished post-medieval Gull Farm and a former pond adjacent to Furze Common have also been identified; both these features are recorded on historic mapping. Based on the results of the survey the archaeological potential of the areas in and around the five locations where anomalies of possible archaeological origin are identified is assessed as moderate. The archaeological potential of most of the PDA is however regarded as low. |
